SPECIFICATION forming part of Letters Patent No. 401,536, dated April 16, 1889.

Application filed January 5, 1888. Serial No. 259,906. o model.)

Patented in England September 28, 1884, No- 13,008.

To all whom it may concern:

Be it known that I, WILLIAM WILLIAMs BOX, a subject of the Queen of Great Britain, and a resident of Crayford, in the county of Kent, in England, have invented certain new and useful Improvements in l mbrella- Frames, (for which I have obtained Letters Patent in England dat 3d the 28th day of September, 1884, and numbered 13,008,) of which the following is a specification, reference being had to the accompanying drawings.

The object of this invention is to construct an umbrella-frame which, while possessing strength and stiffness, shall be light and capable of folding up in a small compass.

Referring to the accompanying drawings, Figure 1 is a side View, about half-size, of part of an umbrellaframe constructed according to my invention and showing the stick, one rib, stretchenand the runner. Fig. 2 is an enlarged part longitudinal section of the upperpart of the stick and parts connected therewith. Fig. 3 is a part sectional plan of same with shoe removed. Fig. 3 is a detail side view of the top notch. Fig 4 is a plan section of the stick. Figs. 5 and (3 show the upper end of rib in side elevation and plan, respectively. Fig. 7 shows those parts of the rib and stretcher where they are connected. Fig. 8 is a plan of part of the stretcher. Figs. 9 and 10 are cross-sections on lines a b and c d, respectively, Fig. 7. Fig. 11. is a sectional elevation of the runner alone; and Fig. 12 is a plan section of same on line 6 f, Fig. 11, but on the stick, which is also shown in section.

I make the stick proper, A, tubular and of a fluted section, as shown in Figs. 1, 4, and 12, somewhat of the contour of a tooth-wheel pinion, the spaces orflutings being of the number of the ribs (usually eight, as shown) which are to rest therein when the umbrella is folded up. The stick proper may suitably be made of brass tubing which is passed through a succession of rolls. The tubular stick so obtained I fill with some light Inaterialpreferably gutta-percha-and in this manner I obtain a very light and at the same time stiff umbrellastiek that is capable of better resisting the strain thereon than would a stick of wood or of gutta-percha alone. here I the guttapercha is run into the fluted stick while in a plastic condition, a fluted core, A, is obtained upon which the metallic fluted sheath fits accurately, as will be readily understood.

The ribs B are of a kind of T shape and made of thin flat steel ribbon-wire bent up into that shape, as shown at Figs. 9 and 10. The ribs B are at their upper end formed with a hole, as shown in Figs. 5 and 6, for eonnection to the top notch, D, by means of a wire. The top notch, D, as shown in Figs. 2, 3, and 3, is provided with notches for the upper end of each of the ribs. The end of the stick A is filled with a screwed plug, A.

The plug A is formed with one or more flat 6 5 faces, as. shown in Fig. 3, and the top notch is kept from moving round thereon by means of the key so, whereby the ribs B in the notch are also prevented from turning on the stick A.

E is a grooved collar round which the cover is sewed. This collar E goes over the upper part of the top notch, D, and is prevented from turning round by a flat face formed thereon. The usual cloth ring or washer, O, is squeezed between and held by the screwed part of the shoe or ferrule A and the collar E. The screwed plug A takes into the screwed part of the shoe-ferrule A said shoebeing made in the form of a tube with a steel plug at the end in place of the ordinary ferrule. I prefer to fill the stick with gutta-percha or the like, whereby the substance of the stick may be lightened without loss of strength.

The runner K is, as shown in Figs. 11 and 12, made of a fluted section to work on the correspondingly-fluted stick A.

L is a spring-catch which is arranged in one of the flutings of the runner. This catch L slips with its upper end into holes at suitable places in. the flutings of the stick, thus seeur- 9o ing the parts of the umbrella in the open or closed position, respectively.

By constructing the runner as described it is perfectly guided on the stick, while the ribs and stretchers arrange themselves in a regular 9 5 manner when folded. The fluted runner also affords a recess for the catch L to lie in.

The stretchers M, as shown in Figs. 1, 7 S,

9, and 10, are connected atone end to the runner K in the ordinary way, and at the other to the ribs 13 by means of the j oint-piece or git G, and are of a V or U shaped section to fit in or onto the T-shaped ribs, and I insure their taking their proper places in relation to the ribs when the umbrella is folded up by bending them, as shown in Fig. 7, and by reason of the perfect guide which the runner has on the stick.

Having fully described myinvention, what I desire to claim and secure by Letters Patent is- 1. An umbrella-stick comprising a fluted core and a correspondingly-iiuted sheath fitted on said core, substantially as and for the purposes specified.

2. An umbrella-stick comprising a core of some light material, a sheathing fitted around said core, and a screw-threaded end plug, A, substantiallyas and for the purposes specified.

In an umbrella, a tubular stick having the plug A, in combination with the shoe or ferrule A substantially as and for the purposes specified.

4. In an umbrella, a fluted stick provided with a depression between two ribs of the fluting, with stop notches or holes, in combination with a correspondiugly-fluted runner, and a spring-catch pivoted between two ribs of the 'fluting and projecting through an aperture in the runner to engage the stop-notches on the stick, substantially as and for the purposes specified.

5. The fluted tubular stick A, having plug A, in combination with the shoe A and top notch, D, substantially as described and shown.

6. The combination, with an umbrella-stick the ferrule end whereof is screw-threaded exteriorly for a portion of its length, said screwthreaded portion being provided with a fiat locking-face, the top notch, D, loosely mounted on said threaded end, and the key :11, engaging the top notch and said flatface on the threaded portions of the stick to lock said parts against rotation, of the collar E, mounted and held against rotation on the top notch and provided with a peripheral groove, and the shoe or ferrule A screwed onto the threaded end of the stick, substantially as and for the purposes specified.

7. The umbrella-frame consisting of the fluted tubular stick A, with screwed plug A, in combination with the top notch, D, grooved collar E, shoe A ribs B, stretchers M, and fluted runner K, with spring-catch L, substantially as described and shown.
